Transurethral resection of the prostate (TURP)

Page contents

Overview

A transurethral resection of the prostate (TURP) is a surgical procedure that involves cutting away a section of the prostate.

The prostate is a small gland in the pelvis only found in men. It's located between the penis and bladder, and surrounds the urethra (the tube that carries urine from the bladder to the penis).

If the prostate becomes enlarged, it can place pressure on the bladder and urethra. This can cause symptoms that affect urination.

Why TURP is carried out

TURP is often recommended when prostate enlargement (benign prostatic hyperplasia) causes troublesome symptoms and fails to respond to treatment with medication.

Symptoms that may improve after TURP include:

problems starting to urinate

a weak urine flow or stopping and starting

having to strain to pass urine

a frequent need to urinate

waking up frequently during the night to urinate (nocturia)

a sudden urge to urinate

being unable to empty your bladder fully

How TURP is performed

TURP is carried out using a device called a resectoscope, which is a thin metal tube containing a light, camera and loop of wire. This is passed along your urethra until it reaches your prostate, which means no cuts (incisions) need to be made in your skin.

The loop of wire is then heated with an electric current and is used to cut away the section of your prostate that is causing your symptoms. A thin tube called a catheter is then inserted into your urethra to pump fluid into the bladder and flush away pieces of prostate that have been removed.

General or spinal anaesthesia is used during the procedure so you don't feel any pain while it's carried out.

Recovering from TURP

You'll usually need to stay in hospital for one to three days after your operation.

The catheter used during the operation will be left in place while you're in hospital because your urethra will be swollen and you may not be able to urinate normally at first.

It's common to feel tired and under the weather for a week or two after going home. Most men are up and about after this time, but you'll need to take things easy for four to eight weeks.

You'll usually be advised to stay off work and avoid lifting heavy objects, doing strenuous exercise, driving and having sex for at least a few weeks.

It's normal to have some difficulties urinating and some blood in your urine for a few weeks. These problems should get better as you recover, but you should contact the hospital clinic or your GP if you're concerned.

What are the risks?

In most cases, TURP is a safe procedure and the risk of serious complications is very small.

However, many men who have a TURP lose the ability to ejaculate semen during sex or masturbation, although they still have the physical pleasure associated with ejaculation (orgasm). This is known as retrograde ejaculation.

Many men also temporarily lose the ability to control their bladder (urinary incontinence), although this usually passes in a few weeks. In rare cases, it may be persistent and need further treatment.

Alternatives to TURP

There are a number of alternatives to TURP that can be just as effective with a lower risk of complications.

They include:

holmium laser enucleation of the prostate (HoLEP) – a laser attached to a resectoscope is used to cut away excess prostate tissue

transurethral laser resection or vaporisation of the prostate – a thin tube called a cystoscope is inserted into the urethra and a laser attached to the cystoscope fires pulses of energy to burn away prostate tissue

However, these procedures aren't suitable for all men with prostate enlargement and may not be widely available.

They may be more suitable for men with very large prostates, older men who are not fit enough to have TURP, and those using blood-thinning medication such as warfarin.
